Whatsapp cannot be use to search for someone`s contact number since it only add your friends directly to your contact list, There is no way you can search someone`s phone number if not save to your contacts.
Since you`re asking if you can have the means to determine someone`s contact through whatsapp. Its impossible. First, if the user don`t use whatsapp, basically he cannot be reached by whatsapp. Searching for his account user info is totally imposible. You must need his Phone number, save it under your contacts and manually input it on `Search a Friend` tab under whatsapp.

Now since communications today are all accessible openly, why not try to chat these friend one day and ask him to use whatsapp and get his number or if you both have Facebook account, chat him out and introduce whatsapp so you can add him and get his contact number.

Want to read messages from another person is access to private information and is considered illegal.

Messages are saved either in the phone or on the same memory card, therefore, to access the messages would have to view them directly on the phone or on the Internet of the application server, but only if you have access to the account.

There are spy applications that are not completely legal, and you can download them to your phone.

Whatsapp syncs your phone`s contacts to use as its own friends list. If you already have your friend added in whatsapp, his contact info should already be in your phone. If you are trying to find out your friend`s contacts, then you`ll need to get them and add it individually to your list.

English: I think you should keep in mind that reading someone`s messages is an invasion of their privacy, Can you imagine if someone read your private messages?, the only way I think you can do that is by reading them directly from that person`s cellphone.

Sorry but you need to login their account first to view the messages. If you don`t know the account details of the person you cannot view their personal messages. As of now there are no spying apps that can be used on whatsapp.

Sorry but whatsapp patched all the glitches that can do that. People are using Whatsapp because of its safety and they will do anything to avoid safety issues. You can only view the messages that are on your account.
